Talk to me about lifetimes of Boxed RC Mutex then… because last time I checked, I had to do some insane amount of <T> to get a concurrent collection synchronize

Talk to me about lifetimes of Boxed RC Mutex then… because last time I checked, I had to do some insane amount of <T> to get a concurrent collection synchronized. I’m all for functional. Just don’t over use it in places where a simple function would suffice and try not to use it when dealing with recursive allocations of temporary arrays. Rust has come a long way but I feel like some of their style choices were to feel superior rather than make something functional. Go is a great example of simple, functional, but not quite as robust - as Rust.
